My attitude has become to buy high-end tools because even if I don’t use them again, I got the best possible experience when I did to decide whether it was worth it, and chances are I can resell it (keeping the box and all accessories) for barely enough discount to have rented some piece of shit that I couldn’t choose to keep if I wanted to.
And bad tools make bad products. A tablesaw that can’t cut a straight line and starts to wobble after 10 uses doesn’t make you want to keep doing that. When I’ve replaced a bad tool with a good one, I like the feeling I get when it just works properly.
I’ve bought enough cheap-shit tools over the years to change my attitude entirely on this. I’ve gotten lucky sometimes, but usually you pay for what you get.
I would be pretty concerned about the safety of yourself and your family. You might want to contact police so they can keep you apprised of his movements and if he’s out on bail, or later when and if he’s out of prison.
He’s expressed some pretty concerning attitudes about you and your mother, and the remark about your wife is strange. I wouldn’t arrange any meeting with him that isn’t well supervised. And if he knows where you live and work, you might consider changing that and keeping the new locations quiet, even from your mother, as she doesn’t sound smart enough to keep it to herself. Get a PO box if you need her to send you anything.
